The Ultra Splice has a glass reinforced Liquid Crystal Polymer (LCP) plastic housing with outside dimensions of 40 mm in length and 5.7 mm in diameter (max). The splices are individually packaged and have a weight of 0.86 grams each. Average splicing loss is less than 0.2dB and is tunable for minimum loss. Mean loss is less than 0.07dB and is tunable for minimum loss. Back reflection (return loss) is -50dB, and loss variation during thermal cycling (-40 to +80 ºC) is less than 0.1dB. One splice accepts any combination from 250-900 microns for coating (buffer size), and fiber retention is greater than 1250 grams. Installation time is 30 to 45 seconds after fiber preparation.
